Which market carries the priciest options
IV30 is the 30-day at-the-money implied volatility; the expected move uses the expiry about two weeks out; skew is 25-delta put IV minus call IV, so a positive value means puts are pricier. Data as of 2026-11-07 21:42 (UTC+8), CBOE delayed by about 15 minutes.

Where implied volatility is highest right now
Bar length is relative IV30; the figure on the right is the expected move into the next expiry. Whether that is rich or cheap depends on where IV sits in its own one-year range — open a market to see its IV rank.
Three numbers are enough
The implied volatility of the 30-day at-the-money option: what the market will pay for 30 days of movement. It says nothing about direction.
IV30 placed inside its one-year range: 0 is the yearly low, 100 the yearly high. High means options are expensive, low means cheap.
A one-standard-deviation move implied by at-the-money option prices: how far the market thinks price will travel into expiry. Roughly seven times in ten it stays inside.
